Dosimeter
Résumé
This dosimeter comprises: - a transducer material (30) able, when it is excited by a secondary ionising radiation, to generate photons or electric charges, - an amplifying layer (34) able, in response to its excitation by primary ionising radiation, to generate the secondary ionising radiation. This amplifying layer (34) comprises a first and second amplifying sublayer stacked one on top of the other. The first and second amplifying sublayers are composed of at least 70%, by mass, of at least a first and a second material respectively, the atomic numbers of which are greater than or equal to twenty-nine. The atomic number of the first material being less than the atomic number of the second material. The first sublayer is interposed between the second sublayer and the transducer material.
